Working on water quality

Monday 14 09 2020

The Flemish Government, Port of Antwerp and SeReAnt (a joint venture between Jan de Nul and DEME Group’s environmental companies) are tackling the port's historical water pollution. The presence of TBT in the water adversely affects the environment. Its clean-up will take about 20 years.

After years of research, there is now a solution for dredging and processing the Antwerp docks' most polluted sludge. "A worldwide first and a milestone for Flanders and Port of Antwerp," says Lydia Peeters, Flemish Minister for Mobility and Public Works. The initiative substantially improves the water quality in the docks, a strategic priority for Port of Antwerp.  


Since the 1970s, TBT has been used worldwide in ship paint to prevent the growth of mussels and algae. However, since 2003, it has been banned altogether. TBT is harmful to humans and the environment and is difficult to degrade. By using activated carbon filters, AMORAS can now also process this polluted sludge from the docks. Eliminating this historical pollution will ultimately benefit the docks’ water quality.
